Abstract
The results of studies of vermiculite rock from the Tebinbulak deposit are given. It is established that this vermiculite rock consists of biotite mica minerals. The crystalline lattice of these minerals contains interpack water known as zeolite water, which is responsible for swelling of the rock in heating. Vermiculite rock fired at 200–900°C is capable of absorbing water, i.e., of rehydration. This is important in using swelled vermiculite in the production of fire-retardant paints. The compositions of fire-retardant paints and the results of their testing for heat resistance according to GOST 30402 are given. It is established that all the developed mixtures impart fired-retardant properties to timber.
